Shu, BDGP) to Release 3 by the BDGP and promoted to Releases 4 and 5 by FlyBase. Sequences submitted since 2003 aligned to Releases 4 and 5 by NCBI and submitted to FlyBase. Some genomic DNA submissions, including TPA submissions, are included in this tier.
EST ("expressed sequence tag") Indicated in light green. Partial sequence of a cDNA; shows the exon (wider bars) and intron (narrow bars) structure, and direction of transcription. D. melanogaster EST sequences submitted to the sequence databases prior to 2003 aligned using sim4 (Florea, et al., 1998, Genome Res. 8:967-74) to Release 3 by the BDGP and promoted to Releases 4 and 5 by FlyBase. D. melanogaster EST sequences submitted since 2003 aligned to Releases 4 and 5 by NCBI and submitted to FlyBase.

Sequences are aligned to Release 5 by NCBI and submitted to FlyBase. These mRNA sequences frequently reflect composite assemblies of a conceptual transcript and therefore may not be available as reagents.

Mapped Mutations
Transgene insertion site SO:0000368 Indicated by blue triangles with an arrow or diamonds with no arrow. An insertion indicated by a downward-pointing triangle and an arrow pointing to the right is oriented with its conventional 5' terminus to the left (assuming view is in conventional orientation of the Drosophila chromosome); this is described as being in the "plus" orientation. An insertion indicated by a upward-pointing triangle and an arrow pointing to the left is oriented with its conventional 5' terminus to the right (assuming view is in conventional orientation of the Drosophila chromosome); this is described as being in the "minus" orientation. An insertion indicated with a blue diamond has an unknown orientation. For all insertions, if the estimated insertion site is larger than 10 nucleotides, there are short dashes on either side of the triangle or diamond. In those cases, see the Insertion Report for more information about localization. Insertions are hyperlinked to their respective Insertion Report. NOTE: If the "Flip" option is selected, the orientations of the insertion triangles do not change and thus will be incorrect. For a guide on how to work out the orientation of an insertion relative to a transcript of interest, see this short powerpoint presentation (download).

The Bloomington Deficiency Kit:
The Bloomington Deficiency Kit is a set of stocks defined by the Bloomington Drosophila Stock Center (BDSC) to provide maximal coverage of the genome with the minimal number of deficiencies having molecularly mapped breakpoints. The BDSC Deficiency Kit also includes deficiencies with breakpoints that have not been mapped molecularly, primarily to provide coverage of gaps between the molecularly defined deficiencies. Since the ends of cytologically characterized deficiencies cannot be placed on the genome map with certainty, the BDSC has defined segments of these deficiencies that fill gaps in molecularly defined coverage for GBrowse display. The endpoints of gap filling segments are derived primarily from overlapping deficiency endpoints and complementation with annotated genes.
BDSC Deficiency Kit: deleted segment Molecularly defined deficiencies are indicated in red. Click the deficiency to go to the Aberration Report. Links to the relevant Stock Report can be found at the bottom of the Aberration Report.
BDSC Deficiency Kit: gap filling or haploinsufficiency flanking segment. Segments of cytologically defined deficiencies that fill gaps between molecularly defined deficiencies or flank haploinsufficient loci are indicated in yellow. Click the segment icon to go to the Aberration Report for the full deficiency. Links to the relevant Stock Report can be found at the bottom of the Aberration Report.
